Fixed Inductors

An inductor, also called a coil or reactor, is an electrical component consisting of a coil of wire, the purpose of which is to store energy in the form of a magnetic field. The inductor can be thought of as a kind of battery; its function is to store electrical energy. Inductors are used in many applications, including in power supplies, signal transmission circuits, and audio circuits. One popular type is the IRF46ER222K.

Application Field
The IRF46ER222K is a surface mount, radial leaded fixed inductor that offers very high inductance in a small form factor. It is commonly used in various types of electronic circuits, such as CD players, DVD players, radios, cellular phones, and other high-frequency applications. Additionally, this type of fixed inductor is used for power conversion and voltage regulation in power supplies.

Working Principle
An inductor is an electronic component that works on the principle of electromagnetic induction. It is made up of a loop of wire that carries an electric current. When the current flows through the wire loop, it creates a magnetic field around it. This magnetic field induces an electromotive force (EMF), which in turn produces a current in the wire loop. This is known as self-induction and is the basis of how an inductor works.

The IRF46ER222K is designed for high frequency operation and uses an oxide coated ferrite core to help with inductance. Its high surge current rating (2A max.) makes it particularly suitable for high frequency switching applications as it can handle large transient currents. It is also rated for a wide temperature range of –55°C to +125°C, ensuring reliable operation in a variety of environments.

In addition to its functional capabilities, the IRF46ER222K offers a very competitive price point and is one of the most affordable high-performance fixed inductors available on the market. This makes it a cost-effective choice for applications such as industrial automation, medical equipment, and consumer electronics.

Overall, the IRF46ER222K is a highly capable and reliable fixed inductor, offering a combination of performance, value, and durability that makes it a popular choice for a variety of electronic applications.
